    Using a 5v hall sensor to 3.3v eensy 4.1 via SN74 difficulty.

    Hi all, I got my hands on a few DC motors (no label/name except 12v/5A and hall sensor name sharpied on it) with this hall effect sensor soldered to it. Pages 4&5 have the specs. I have a 5V power supply used for the sensor. set up: Same code, different pins used, difference is using this...
